    Abstract: A method of making a lithographic printing plate comprising the steps of:
    a) providing a lithographic printing plate precursor comprising
    (i) a support having a hydrophilic surface or which is provided with a hydrophilic layer,
    (ii) a coating on said support comprising a photopolymerizable layer,

    b) image-wise exposing said coating in a plate setter,
    c) heating the precursor in a preheating unit,
    d) treating the precursor in a gumming station, including at least a first gumming unit, by applying a gum solution to the coating of the precursor whereby the precursor is developed and gummed in a single step and whereby said gum solution remains on the plate as a layer, and wherein said gum solution comprises a surface protective compound selected from a film-forming hydrophilic polymer and/or a surfactant,

    characterized in that the preheating unit and the gumming unit are coupled to each other by mechanical plate conveying means or are integrated in a single apparatus.

    Abstract: A relief print master is created by printing a sequence of layers on top of each other by means of an inkjet printing system. The top layer corresponds with the binary halftoned image that is to be printed by the print master and the lower intermediate layers are supporting layers. The features in a lower supporting layer have an area that is larger than the corresponding features in a higher supporting layer. A circular spread function is applied on the features of a higher intermediate layer to increase the area of the features in a lower intermediate layer. By using a sequence of two non-circular spread functions, the circular spread function is approximated and the number of required calculations can be reduced.

    Abstract: A gum solution is provided which comprises a film- forming hydrophilic polymer or surfactant, and a salt formed by reaction of an acid, selected from phosphoric acid and phosphorous acid, with a di- or tri-alkanolamine. The gum solution is suitable for developing and gumming a lithographic photopolymer printing plate precursor. Also provided is a method for preparing a lithographic printing plate wherein this gum solution is used, and whereby printing plates are obtained which exhibit an improved clean-out performance.

    Abstract: A method for making a lithographic printing plate precursor is disclosed comprising the steps of a. providing a lithographic printing plate precursor including a support having a hydrophilic surface or which is provided with a hydrophilic layer, a photopolymerizable coating comprising a photopolymerizable composition, and an overcoat layer comprising a water soluble low molecular weight acid, wherein said overcoat layer has a surface pH-value ranging between 1 to 6; b. image-wise exposing the precursor; c. optionally heating the exposed precursor; d. processing the obtained precursor by applying a gum solution and optionally brushing the precursor, and/or by mounting the precursor on a plate cylinder of a lithographic printing press and rotating the plate cylinder while feeding dampening liquid and/or ink to the coating. The printing plate obtained after imaging and processing in an off-press configuration with a gum solution or in an on-press configuration with fountain solution and ink shows an improved roll-up performance in the start-up of a printing process on a printing press.
